Hi,
I was trying to use this particular option of grep
grep -r 'Search_pattern' *
This command should ideally search all the occurrences of Search_pattern recursively within a directory & print it on shell prompt. But this command is not doing what is expected. It just displays nothin!

Greetings all. :)
I would like to use sed to join all non-blank lines together in a particular file. I was thinking I could do this by simply replacing the terminating, new-line character on every line which is not blank, but I must be missing something in my sed line:

Hi.
I'm new to this forum, my English perhaps is not so good, but here is my question:
In bash you can use ] for tests, and how I understand it the variable names should be expanded automatically. So this should give "yes":

$ ] && echo yes || echo no
no # not giving "yes"
These two... (2 Replies)

Hi All,
I've tried starting syslogd on our hp-ux 11.31 server. However, it is not getting started nor it is updating the syslog file.

stream_socket_recvfrom
STREAM_SOCKET_RECVFROM(3) 1 STREAM_SOCKET_RECVFROM(3)stream_socket_recvfrom - Receives data from a socket, connected or notSYNOPSIS
string stream_socket_recvfrom (resource $socket, int $length, [int $flags], [string &$address])
DESCRIPTION stream_socket_recvfrom(3) accepts data from a remote socket up to $length bytes.
PARAMETERS
o $socket
- The remote socket.
o $length
- The number of bytes to receive from the $socket.
o $flags
- The value of $flags can be any combination of the following:
Possible values for $flags
+------------+---------------------------------------------------+
| | |
|STREAM_OOB | |
| | |
| | Process OOB ( out-of-band) data. |
| | |
| | |
|STREAM_PEEK | |
| | |
| | Retrieve data from the socket, but do not con- |
| | sume the buffer. Subsequent calls to fread(3) or |
| | stream_socket_recvfrom(3) will see the same data. |
| | |
+------------+---------------------------------------------------+
o $address
- If $address is provided it will be populated with the address of the remote socket.
RETURN VALUES
Returns the read data, as a string
EXAMPLES
Example #1
stream_socket_recvfrom(3) example
<?php
/* Open a server socket to port 1234 on localhost */
$server = stream_socket_server('tcp://127.0.0.1:1234');
/* Accept a connection */
$socket = stream_socket_accept($server);
/* Grab a packet (1500 is a typical MTU size) of OOB data */
echo "Received Out-Of-Band: '" . stream_socket_recvfrom($socket, 1500, STREAM_OOB) . "'
";
/* Take a peek at the normal in-band data, but don't comsume it. */
echo "Data: '" . stream_socket_recvfrom($socket, 1500, STREAM_PEEK) . "'
";
/* Get the exact same packet again, but remove it from the buffer this time. */
echo "Data: '" . stream_socket_recvfrom($socket, 1500) . "'
";
/* Close it up */
fclose($socket);
fclose($server);
?>
NOTES
Note
If a message received is longer than the $length parameter, excess bytes may be discarded depending on the type of socket the mes-
sage is received from (such as UDP).
Note
Calls to stream_socket_recvfrom(3) on socket-based streams, after calls to buffer-based stream functions (like fread(3) or
stream_get_line(3)) read data directly from the socket and bypass the stream buffer.
